Guardian Assurance Company Limited v Condogianis

Guardian Assurance Company Limited (the appellant) appealed to the High Court of Australia from a judgment of the Supreme Court of Victoria. The dispute concerned a policy of insurance issued by the appellant to the respondent, Mr. Condogianis, in respect of a motor vehicle. The respondent claimed indemnity under the policy for damage sustained to the vehicle. The appellant denied liability, alleging that the respondent had made material misrepresentations and failed to disclose material facts when applying for the policy.

The High Court was required to determine whether the respondent had made misrepresentations or failed to disclose material facts that would entitle the appellant to avoid the policy. Specifically, the court had to consider the nature of the duty of disclosure owed by an insured to an insurer at the time of entering into a contract of insurance, and whether the respondent's statements and omissions regarding his driving history and the intended use of the vehicle constituted a breach of that duty.

The court applied the principles of insurance law concerning the duty of utmost good faith (uberrimae fidei) that governs contracts of insurance. It was held that the respondent was under a duty to disclose all material facts known to him that might influence the judgment of a prudent insurer in deciding whether to accept the risk and, if so, on what terms. The court found that the respondent had failed to disclose that he had previously had a proposal for motor vehicle insurance declined and that he intended to use the vehicle for commercial purposes, which were both material facts. Consequently, the appellant was entitled to avoid the policy.
